I have a user control that has a combo box in it. I've placed this user control onto a windows form that has other controls on it.
When I open a combobox on the user control at runtime, the mouse scroll wheel will not scroll the combobox.
Any combobox on the form not in the user control scrolls the combo box content.
How do I make the user control combo boxes act the same?
Thanks,
Tim

Hello,
I am trying to figure out the format of data to send over CAN bus (using PCAN) using Vb.net. How would i be encoding and decoding data.
i would really appreciate if some one can help me.
Thanks.

Since this is such an obscure question, this[^] is the first thing anyone is going to do to start researching an answer.

Hi,
I have done lots of CAN (not PCAN) stuff in C some years ago, on embedded
systems, not on PC. We used our own protocol on CAN and other networks.
What hardware are you using? Did it come with a driver? What is it the
driver expects? Does it offer a .NET interface, or are you looking into
P/Invoke? Do you have any PCAN library source code available, if so, in what
language is it?
I would expect a CAN driver wants a destination address (or CAN-ID), a priority,
and a number of data bytes. I would guess the PCAN protocol can be
implemented on top of that in whatever language you choose. And I would
try and stick to a byte array to carry the data.
Hope this helps.

hi, i've a yahoo mail account..
how can i send mail in vb.net whith my account credentials ??
can you post code ? thanks
|

I don't think Yahoo allows SMTP. Google search for it. There are more examples of that code out there than any other (other than the "save image to database" code).
|
|
|
|
|
AFAIK, Yahoo doesn't expose any SMTP servers and they don't supply an API to do this either. It looks like your idea isn't going to work, unless someone else knows something we don't.

|

|
|
Perhaps instead of yahoo, create and use a GMail acct. There are numerous tutorials on how you can tie into Google Mail.
Cheers!

It does have SMTP -- this is an example if you have att's dsl through yahoo.
note #1: the from email and the credentials must be the same
note #2: if you login into your email, you can get the other smtp names for the type of email address extention you have (@yahoo.com / @att.com / @ameritech.com / etc)
Dim oMsg As New MailMessage
With oMsg
.From = New MailAddress("XXXXXXX@ameritech.net")
.To.Add("THEONEIWANTTOSENTO@HOTMAIL.COM"
.Priority = MailPriority.Normal
.Subject = "Test"
.Body = "test"
End With
Try
Dim oSMTP As New SmtpClient("smtp.att.yahoo.com")
oSMTP.Credentials = New NetworkCredential("XXXXXXX@ameritech.net", "ABCDEFG")
oSMTP.Send(oMsg)
oSMTP = Nothing
Catch ex As Exception
MessageBox.Show("Could not send the status email message." & ControlChars.CrLf & ex.ToString, _
"Emailing", MessageBoxButtons.OK, MessageBoxIcon.Stop)
End Try

Hi,
your Internet provider typically also offers a mail service, which is
adequate to send out mail messages, even if you choose not to use it
to receive anything.
Then a simple piece of code will do the job, based on MailMessage
and SmtpClient classes. Here is a C# snippet for you (the very same thing
can be done in VB.NET):
MailMessage msg=new MailMessage();
msg.From = ...;
msg.To.Add(...);
msg.CC.Add(...);
msg.Subject=...;
msg.Body=...;
SmtpClient client = new SmtpClient(server);
client.Send(msg);
And the surprise is you can assign any valid mail address to the From
property, so you could well make it look as if you used your Yahoo account to
send the message, although you did not.
BTW: server is the mail-out server of your provider, a typical example
in Belgium would be "relay.skynet.be" or "relay.belgacom.be"

how to convert string to binary and vice versa
thanks
|
|
|
|

This type of question should not be posted. You can find your answer in HELP.
Here is what came up when I serched for "convert string to number"
VB Example:
Dim value As String
Dim returnValue As Integer
returnValue = Convert.ToInt32(value)
Next time, take some initiative to find the answer for yourself.
Also read the following article before posting again.

I wrote an article here[^] that simplifies this. The code is C# but easily converted. If you just want the dll, extract BinOctHex.dll from the zip in the Download Sample link.
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

Hello all,
I am looking for something similar to the scrolling grid in the week view on google calender.
I looked at
http://www.codeproject.com/aspnet/ScrollingGrid.asp
and it looks pretty good but I need the column widths to change size along with the browser, and have a fixed header that does the same. I have looked around but I'm not really sure on what areas to look at. Any help would be greatly appreciated.

Hello,
I have maybe a stupid question.
I have a .net 2008 application form , when clicking on a button on the mainform i opens a second form on top of it.
i set the mainform disabled so it is not possible to touch the main form wich is bigger than teh form on top.
In the taskbar the 2 forms are visible , when clicking on the mainform in the taskbar. the mainform becomes on front od the smeller form but the main form is disabled so the programm is not accesible anymore.
Is there a solution so i can remoe the forms from the taskbar so that it is not possible to click on it.
Thanks

Check out the ShowInTaskBar property of the Form.
|
|
|
|

Ditto to JZ. Sounds like you might want to show it modal as well like, form1.ShowDialog

Environment :
I have developed an Application in VB.NET and Reports are in CrystalReports 10.
The Problem is : I call the CrystalReport rpt file using VB.NET. The crystal Report page contains the map of the USA cities and States.
In Crystal Report if i run the RPT file and move the cursor on the map, the Tool tip shows the Name of the State and Cities.
if i call the Same file using VB.NET, the report shows on IE. If i move the cursor on the map, Nothing is displayed..
So tell me what should i do to show the Cities and States as a Tool tip while calling the Crystal Report rpt file using VB.NET?
Reply Soon............... Waiting...........
Reagrds and Thanks in Advance

Please, Keep in mind that the Crystal Report does not run on the web.
Because, It Uses The Server Controls that should be Buy from The Business object. The Crystal Reports You are using in the vb.net it just a small copy of the Business Object's Crystal Reports.
